In general one would say that amplitude does not affect frequency, but if you look at a practical example, you can see that, under certain conditions, amplitude must affect frequency.
When you pluck a guitar string, giving the string, say, a very large displacement - which results in a very large amplitude wave - the tension of the string will increase according to the displacement of the string from its neutral position, and the tension of the string does affect the frequency, so a larger displacement will have the effect of increasing the strings average frequency.

No. Amplitude has to do with the magnitude of the wave.
